V+ Internally generated positive supply (+10V nominal).
V- Internally generated negative supply (-10V nominal).
GND Ground Lead. Connect to 0V.
C1+ External capacitor (+ terminal) is connected to this lead.
C1- External capacitor (- terminal) is connected to this lead.
C2+ External capacitor (+ terminal) is connected to this lead.
C2- External capacitor (- terminal) is connected to this lead.
T Transmitter Inputs. These leads accept TTL/CMOS levels. An internal 400kW pull-up resistor to V
IN
T Transmitter Outputs. These are RS-232 levels (nominally ±10V).
OUT
R Receiver Inputs. These inputs accept RS-232 input levels. An internal 5kW pull-down resistor to GND is connected to each input .
IN
R Receiver Outputs. These are TTL/CMOS levels.
OUT
EN, EN Receiver Enable Input. With EN = 5V (HIN213E EN=0V), the receiver outputs are placed in a high impedance state.
SD, SD Shutdown Input. With SD = 5V (HIN213E SD = 0V), the charge pump is disabled, the receiver outputs are in a high impedance
state (except R4 and R5 of HIN213E) and the transmitters are shut off.
NC No Connect. No connections are made to these leads.
